Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

What is the air that surrounds the earth called?
It is called the Atmosphere.
What is the difference between wet air and dry air?
the answer is atmosphere and trosphere
How would the world be without air?
exactly is the atmosphere if it is not just air
Why does air cool when it rises through the atmosphere what is this type of cooling known as?
Air cools becuase when its rising through the atmosphere altitude decreases temperature, and when air rises its temperature drops at the dry abiatic rate. This type of cooling is known as adiabatic.
What is where air is pushing down with more pressure?
atmosphere
Is the composition of air same through out the atmosphere?
No.
Why is the amount of gases in the atmosphere usually shown as percentages of dry air?
Showing the amount of gases in the atmosphere as percentages of dry air allows for easy comparison and analysis of the composition of the atmosphere. Since the composition of dry air is relatively stable, expressing the gases as percentages of dry air helps to standardize the data for scientific purposes.
What is the role of argon in air and how does it affect the composition of the atmosphere?
Argon is a noble gas found in the Earth's atmosphere. It makes up about 0.93 of the air we breathe. Argon is chemically inert, meaning it does not react with other elements. Its presence in the atmosphere helps maintain the overall composition and stability of the air. Argon does not play a significant role in the chemical reactions that occur in the atmosphere, but its presence is important for maintaining the balance of gases in the air.
How many percent is nitrogen composition in the air?
Nitrogen makes up about 78% of Earth's atmosphere.
What are two most common gases in dry air and what percentage of earth's atmosphere composition does each gas make up?
The two most common gases in dry air are nitrogen (N2) at approximately 78% and oxygen (O2) at around 21% of Earth's atmosphere composition.
How much oxygen is in the air in 1973?
In 1973, the composition of Earth's atmosphere was roughly the same as it is today, with oxygen making up about 21% of the air.
What has an effect on air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
What is the composition of the atmosphere on a comet?
A comet has no atmosphere.
What is nitrogen's main function in the atmosphere and how does it contribute to the overall composition of the Earth's air?
Nitrogen's main function in the atmosphere is to act as a non-reactive gas that makes up about 78 of Earth's air. It contributes to the overall composition of the atmosphere by providing stability and diluting the more reactive gases, such as oxygen, to create a breathable mix of gases for living organisms.
